The enable pin is a high-voltage-tolerant pin. A high input on EN actives the device and turns on the regulator. For self-bias applications, connect this input to the IN pin. Ensure that VEN ≤ VIN at all times.
When the enable signal is comprised of pulse-width modulation (PWM) pulses, the slew rate of the rising and falling edges must be less than 1.5 V/µs. Adding a 0.1-µF capacitor from the EN pin to GND is recommended.
